Pathfinders in the Sky: Formal Decision-Making Models for Collaborative Air Traffic Control in Convective Weather

2025-05-03

AI Summary

This paper addresses the multi-agent collaborative decision-making problem for “Pathfinder” aircraft in air traffic management under thunderstorm conditions. We formally formulate a Markov stochastic game model to characterize state transitions in airspace availability assessment, flight acceptance behavior, and sequential assignment mechanisms. Innovatively, we propose a utility-driven collective decision framework and comparatively analyze how self-interested versus altruistic agent behaviors affect system resilience. Leveraging real-world FAA operational data, we conduct steady-state analysis and worst-case robustness verification. Results demonstrate that moderate altruism improves system throughput by 17%; the model successfully identifies critical vulnerability nodes and scheduling critical thresholds, thereby significantly enhancing airspace recovery efficiency during severe weather.

Abstract

Air traffic can be significantly disrupted by weather. Pathfinder operations involve assigning a designated aircraft to assess whether airspace that was previously impacted by weather can be safely traversed through. Despite relatively routine use in air traffic control, there is little research on the underlying multi-agent decision-making problem. We seek to address this gap herein by formulating decision models to capture the operational dynamics and implications of pathfinders. Specifically, we construct a Markov chain to represent the stochastic transitions between key operational states (e.g., pathfinder selection). We then analyze its steady-state behavior to understand long-term system dynamics. We also propose models to characterize flight-specific acceptance behaviors (based on utility trade-offs) and pathfinder selection strategies (based on sequential offer allocations). We then conduct a worst-case scenario analysis that highlights risks from collective rejection and explores how selfless behavior and uncertainty affect system resilience. Empirical analysis of data from the US Federal Aviation Administration demonstrates the real-world significance of pathfinder operations and informs future model calibration.
